巢湖湖岸带鸟类多样性的初步研究

2008年2月、7月、11月到2009年7月,采用路线调查和定点观察相结合的方法对巢湖沿岸及湖滨带不同生境的鸟类种类及数量进行了调查。记录到鸟类15目33科103种,其中属于国家Ⅱ级重点保护的鸟类3种,安徽省地方重点保护鸟类33种。季节型中,留鸟33种,夏候鸟37种,冬候鸟27种,旅鸟9种。繁殖鸟类的地理型中,古北界种23种,占33.3%;东洋界种30种,占43.5%;两界广布种16种,占23.2%。水鸟33种,近湖岸500m以内水面游禽有10种。优势种5种,广布性种15种。在湖岸5类生境中,树林、灌丛和抛荒地鸟类多样性指数最高,湖滨及浅滩鸟类多样性指数最低。湖泊污染和盲目开发导致鸟类栖息地破坏和丧失,影响鸟类多样性,因此应加强湖泊污染治理,恢复沿岸滩涂及其植被,维持巢湖丰富的鸟类多样性。
